It's just a new generation of basically what was PowerFLARM. Saying it can do ADS-B Out in EASA land is kinda meaningless, you can connect up any old NMEA GPS there in a glider. And you can do that here in the USA... which will get you visibility to PowerFLARM units and portable ADS-B In receivers but that is all.

And it's apparently not FCC approved. So not legal to sell in the USA.
